PrOTek’TiOn高级电路保护设备系列产品介绍说明书

Today’s automobile has come a long way since the 1970s when the engine control unit (ECU) – also known as the power control module (PCM) – was first put into play. According to a recent New York Times article, modern cars now have from 30 to 100 microprocessor-controlled devices (ECUs) within. These devices have long been used to control everything from critical safety systems like brakes and airbags; to control convenience features like
telematics and navigation. More and more automobiles come equipped with more and more advanced electronic control systems. However , they are not just being added as features but, also as requirements. For example, direct tire pressure monitoring systems (TPMS) are now required on all new cars sold in the EU. Newer systems now come standard with all types of comfort systems, such as heated / cooled seats and all types of safety systems, such as advanced driver assistance systems with collision avoidance and parking assist features.
Automotive manufacturers continue to turn to IC-based systems for new features and capabilities. With this trend, the need for more circuit protec-tion for these systems also grows alongside. As noted, there are dozens of applications that need circuit protection. They include USB ports, Ethernet ports, CANBus and LINBus lines, antenna, display interfaces, power systems, fuel injection management systems, and many more. Electrical transients present a top critical risk to damaging these systems. Electrical transients also increase servicing and warranty costs for auto manufacturers. Therefore, proper circuit protection is an important factor of any automotive design process.
There are also many mandatory safety systems requiring advanced electronic components while there is an ever-increasing reliance on electronic tech-nologies within the automotive sector . There are many common transients in automotive systems that impact performance of the electronic systems. They can be generated from many different sources, from common electrostatic discharges to disconnecting a battery. Automotive designers of Infotain-ment, lighting, drive-train, body or chassis/safety groupings need to consider the circuit protection to combat these transients.
Automotive electronic systems design engineers should be aware of requirements set forth by the International Organization for Standardization (ISO). ISO 16750 is for road vehicles and covers environmental conditions and testing for electrical and electronic equipment. Released in 2010, ISO 16750-2 was prepared by Technical Committee ISO/TC 22 to replace ISO7637 for load dump, the pulse 5a and 5b portion. Further revisions to ISO 16750-2 were released in 2012. ISO 16750-2 applies to electric and electronic systems/components for road vehicles. It describes potential environmental stresses and specifies tests and requirements for the specific mounting location on/in the road vehicle.
The Automotive Electronics Council (AEC-Q101) provides a discrete semiconductor qualification standard for automotive applications including cir-cuit protection requirements: AEC-Q101-001 (electrostatic discharge [ESD] test - human body model); AEC-Q101-002 (ESD test -machine model); AEC-Q101-003 (wire bond shear test); AEC-Q101-004 (miscellaneous test methods such as unclamped inductive switching, dielectric integrity, and destructive physical analysis); and AEC-Q101-005 (ESD test - capacitive discharge model).
